An artery branches into two smaller veins, identical arteries as shown in the diagram. The largest artery has a diameter of 10 mm. The two branches have the same diameter = 5 mm. The average speed of the blood in the main artery is given in the diagram. The blood has a density of 1004 kg/m^3.

Main artery Vo = 0.50 m/s before it branches out into two veins.

QUESTION: Calculate v, the average blood flow speed in the two branches of smaller radius.
